2. Create a New Material Function
3. Add a Texture Sampler Parameter named Texture with a Group name of Alpha
4. Add a Scalar Parameter named Scalar with a Group name of Beta
5. Add a Vector Parameter names Vector with a Group name of Beta
6. Multiply the Texture Parmeter by the Scalar
7. Add the results to the vector
